[AccessD] Running Access 2003 and 2010 on same PC

Hopefully someone here has resolved multi versions of Access on the same
machine. I'm trying to set up 2010 to run along with the trusty 2003 on XP
sp3. Whenever I move from one version to the other,  I get the Microsoft
interruption and message that M$oft is reinstalling. It seems a very
frustrating issue that would have been solved (officially) or a proper work
around found and used. 
 
I have searched a lot and have not found a definitive solution. I have seen
people who have gone to Virtual PC to separate their different versions of
Office and Access.
 
Has anyone solved this? If you're running multiple versions of Acces on same
PC, do you really put up with the reinstalling/reconfig stuff?
 
Feedback please.........
